Abstract
Embodiments may provide a method for performing a replay of a previous execution of a program. The method includes generating an order of recorded chunks of instructions across a plurality of recorded threads based, at least in part, on log files generated from the previous execution of the program. The method includes initiating execution of the program, the executing program having a plurality of threads, each thread having a number of chunks of instructions. The method includes intercepting, by a virtual machine unit executing on a processor, an instruction of a chunk before the instruction is executed. The method includes determining, by a replay module executing on the processor, that the chunk is an active chunk if the chunk is currently in line for execution according to the order of recorded chunks, and responsive to a determination that the chunk is the active chunk, executing the instruction.
